Crystallization of Magmas part of Activities
John Ayers, Vanderbilt University
Students use three methods to explore the crystallization behavior of a rock of known composition at 1 atmosphere pressure. This laboratory exercise illustrates various approaches used by geochemists and ...

Compositional Diversity in Volcanic Suites part of Activities
Kent Ratajeski, Calvin University
In this exercise, students use geochemical data downloaded from the GEOROC database to explore the origins of compositional variation among volcanic rocks associated with the Yellowstone and Crater Lake calderas.

Crystallization-Differentiation of Basaltic Magma part of Activities
Kent Ratajeski, Calvin University
In this exercise, students use geochemical data from volcanic glasses and minerals in lavas and drill cores from the solidified Kilauea Iki lava lake to learn about the petrologic processes related to the eruption ...

REE Modeling of Melting and Crystallization part of Activities
Mark Schmitz, Boise State University
This exercise is used in and out of class for exploring the use of trace elements to model melting and crystallization processes; it emphasizes quantitative skills and constructing numerical models.
